pavlov (1927)

Question 1

aim

Answer 1

to study how the cerebral cortex works in making associations and to look for a mechanism linking reflexes to cerebral cortex. exploring how salivation becomes associated with new tumuli apparent unrelated to food and the properties of this association

Question 2

procedure

Answer 2

• the dog was restrained in a harness in the cubicle and isolated from all distractions
• observed through a one way mirror
• a tube carried the saliva from the dogs more to a container where it was measured
• isolated the dog in a small room so that even hearing footsteps outside was not possible

Question 3

CC formula

Answer 3

UCS = UCR
(food = salivation)
NS + UCS = UCR 20+ pairings
(metronome + food = salivation)
CS = CR
(metronome = salivation)

Question 4

results

Answer 4

• salivation started after 9 seconds and by 45 seconds, 11 drops had been collected
• the dog would only salivated when the NA/CS was presented before the UCS
• stimulus generalisation to sounds of a similar tone occurred

Question 5

conclusion

Answer 5

pavlov concluded that signalisation in the brain links the metronome to food and thus gives the reflex response of salivation. conditioning was found to be sensitive to many extraneous variables and to individual differences
